In nvkm_device_tegra_probe_iommu(), a paging domain is allocated for @dev
and attached to it on success. Use iommu_paging_domain_alloc() to make it
explicit.

Did you just take this one patch? 

Who will take the rest of the series for DRM?

Jason

I did take the one patch - but I'm happy to push the others to drm-misc
(provided they all get reviewed. 2/3 seems to be reviewed already but not 3/3)

Did it get lost?

$ git reset --hard next-20240913
$ git grep 'iommu_domain_alloc(' drivers/gpu/
drivers/gpu/drm/nouveau/nvkm/engine/device/tegra.c:		tdev->iommu.domain = iommu_domain_alloc(&platform_bus_type);

??

 drivers/gpu/drm/nouveau/nvkm/engine/device/tegra.c |  4 ++--
 drivers/gpu/drm/rockchip/rockchip_drm_drv.c        | 10 +++++++---
 drivers/gpu/drm/tegra/drm.c                        |  5 +++--

Now we have the other two but not nouveau?

Jason

Sigh. Took me a minute but I think I know what happened - I meant to push the
entire series to drm-misc-next and not drm-misc-fixes, but I must have misread
or typo'd the branch name and pushed the second half of patches to drm-misc-
fixes by mistake. So the nouveau commit is present in drm-misc-next, but
presumably drm-misc-fixes got pulled first.

Sorry about that - I have no idea how I managed that mistake.

Three didn't make it to rc1, including this one:

drivers/gpu/drm/nouveau/nvkm/engine/device/tegra.c:             tdev->iommu.domain = iommu_domain_alloc(&platform_bus_type>
drivers/media/platform/nvidia/tegra-vde/iommu.c:        vde->domain = iommu_domain_alloc(&platform_bus_type);
drivers/remoteproc/remoteproc_core.c:   domain = iommu_domain_alloc(dev->bus);

I prefer we send these through the iommu tree now so we can make
progress.

Jason

Fine by me
